A caller to ABC15 said she was on a tour of the stadium when she saw the “roof collapse.”

Glendale Fire Department officials say crews were called to check a hazard at the Cardinals stadium around 4 p.m. Spokesman Daniel Valenzuela said crews checked the roof and decided it was not a hazard.

Air15 video showed what appears to be a portion of the roof torn apart with portions of it lying on the ground nearby. The edge of the roof appeared to be damaged in another section and there was a smaller area of damage in yet another section.
